Paper Abstract

We propose an experimental results and theoretical description of the ultrashort pulse train spectral broadening in tapered fibers. Multi-peak spectral structure due to the effect of self-phase modulation was obtained. Phase and amplitude fluctuations were investigated. Shown that stability of intermode beats decreased slightly after the propagation through tapered fiber. A technique and results of high precision measurements of the intermode frequency of a femtosecond Ti:sapphire laser for investigation of the influence of a tapered fiber are described. The experiments have shown that the intermode frequency stability does not depend on the broadened spectrum range.
